Inflammatory Bowel Disease V: Surgical Management

267
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Summary

High-frequency electric welding offers a novel method for creating secure biliodigestive and interintestinal anastomoses, even in inflamed tissues. This technique ensures hermetic sealing and sufficient strength, preventing future strictures.

Area of Science:

  • Surgical Innovation
  • Gastroenterology
  • Biomedical Engineering

Background:

  • Biliodigestive anastomoses are crucial surgical connections.
  • Current methods can be challenged by inflamed bile ducts.
  • Developing reliable techniques for various tissue conditions is essential.

Purpose of the Study:

  • To develop and evaluate a new method for forming biliodigestive anastomoses.
  • To assess the efficacy of high-frequency electric welding in both healthy and inflamed tissues.
  • To determine the patency, tightness, and strength of anastomoses created by this method.

Main Methods:

  • Experimental study on 50 rabbits (Chinshila breed).
  • Formation of biliodigestive and interintestinal anastomoses using high-frequency (HF) electric welding (Patonmed EKVZ-300 coagulator).
  • Anastomoses created on both non-inflamed and inflamed (biliary peritonitis) tissues, followed by macro- and microscopic examination at various time points.

Main Results:

  • HF electric welding achieves tissue adhesion via thermal bonding, primarily through the submucosal layer.
  • Anastomoses demonstrated hermetic sealing and sufficient strength (40-100 mm Hg).
  • Narrow coagulation scars with localized thermal damage (2700-3000 microns); epithelialization complete in 3 months, scar maturation in 6 months.

Conclusions:

  • HF electric welding is a reliable method for creating biliodigestive and interintestinal anastomoses in both healthy and inflamed tissues.
  • The everting weld connection effectively prevents the development of anastomotic strictures.
  • This technique offers a promising alternative for complex biliary reconstructive surgery.
